Launched ahead of the Guardian’s Open Weekend event this weekend, the Streetstories app provides a guide to King’s Cross,the area of London where King’s Place, the Guardian building where the event will take place, is located.

Streetstories is a free app for iPhone and Android which triggers audio relevant to your location – your smartphone knows where you are, and plays the stories automatically. The way the app works is you plug in your headphones, start up the ‘autoplay’ mode and put your smartphone in your pocket. The app will find where you are and start playing the clips, so you don’t need to press any buttons, just wander anywhere in the area and your route will create your own narrative
